the mother with an injection, the drug is called RhoGAM.
The first child born of a female is generally not at risk for erythroblastosis fetalis because the mother's immune system has not been exposed to the fetal blood antigens and therefore has not produced antibodies against it. However, by the second pregnancy there is a slight risk if the blood type of the fetus is not compatible with the mother's blood type.
http://www.nlm.nih.gov/medlineplus is the website the full URL of the document is http://www.nlm.nih.gov/medlineplus/ency/article/001298.htm This URL leads to a very good article on erythroblastosis fetalis, i couldn't put in the full text, as it is copyrighted, but the website seems very good, this should help you
The second baby, normally. Erythroblastosis Foetalis is when a baby with a positive blood group is born to a mother of a negative blood group, and the mother has been 'sensitized' during a previous pregnancy. The mother's body identifies the fetus as a 'foreign' protein and her body's immune system tries to fight the foreign protein, much like an allergic reaction.
The most severe form of erythroblastosis fetalis is that resulting from Rh incompatibility. But you can have erythroblastosis fetalis with ABO incompatibility as well. And this can occur with any child, even the first, and even with an Rh-negative child. However, if you're referring to Rh-incompatibility erythroblastosis fetalis, the answer to your question is, "Not usually" (assuming she hasn't had a previous Rh-positive child). In Rh-incompatibility, erythroblastosis fetalis occurs with the woman's second Rh-positive child. The first Rh-positive child's blood gets into the mother's bloodstream (e.g. at childbirth). The mother's blood makes antibodies to Rh. Since the first child is already born, this does not affect the first child. Then, when she has a second Rh-positive child, her antibodies cross the placenta and attack that child's blood cells. On the other hand, if the mother is exposed to the Rh factor of the first child's blood earlier in the pregnancy somehow, then I suppose she could develop enough antibodies to cause a problem for that first child.
RHO Gam is used to prevent hemolytic disease of the newborn in cases of Rh incompatibility between the mother and fetus. It works by preventing the mother's immune system from producing antibodies that could harm the baby in future pregnancies.

What is Erythroblastosis?
by giving an Rh negative mother a gamma globulin solution called RhoGAM whenever there is a possibility that she is developing antibodies to her baby's blood.

IgG is the class of immunoglobulin responsible for the development of erythroblastosis fetalis. It can cross the placenta from a mother who is Rh-negative to a fetus who is Rh-positive, leading to hemolytic disease in the newborn.
erythroblastosis is a very serious condition for approximately 4,000 babies annually. In about 15% of cases, the baby is severely affected and dies before birth.
IgG molecules.
Hemolytic disease of the newborn is known as erythroblastosis fetalis
Erythroblastosis fetalis is a potentially life threatening blood disorder in fetus or new born infant. It happens when the mother possesses Rh negative blood where the foetus posses Rh positive blood which turns it weak anaemic nd jaundiced or in severe case death of the foetus occurs..
Erythroblastosis fetalis got its name from the presence of erythroblasts, which are immature red blood cells, in the fetal circulation. The condition occurs when there is an incompatibility between the blood types of the mother and fetus, often due to Rh factor incompatibility. This results in the mother's immune system attacking the fetal red blood cells, leading to anemia and other complications. The term "fetalis" denotes its occurrence during fetal development.
